→ Previously titled "Farmers' Livelihood Strategies to Cultivate in a Secondary Cropping Season for the Schooling of Children: Evidence from Tanzania"

Highlights: To reduce hunger in the lean season, this research sheds light on the short rainy season, a secondary cropping period in East Africa. If farmers cultivate in a secondary cropping period in addition to the main one, they can obtain additional food in a year. One of my papers shows that farmers improve their caloric intakes and dietary diversity by cultivating in the short rainy season. Moreover, this benefit is stronger for resource-poor farmers with small farm size. Another paper shows that welfare improvements are not limited to food security. Additional agricultural income in the short rainy season enables farmers to make their children enroll in and attend schools.

（Papers on crop diversification）

・"Different Strategies of Crop Diversification Between Poor and Non-Poor Farmers: Concepts and Evidence from Tanzania" (with Aya Suzuki) (Revise & Resubmit) pdf

Highlight: It has been widely observed that crop diversification improves farmers’ welfare among the poorest the most. In contrast, poor farmers sometimes struggle to grow multiple crops because they must own enough agricultural resources (e.g., land and seeds). This conflicting nature of crop diversification makes us unsure whether poor farmers are motivated to adopt crop diversification under poverty constraints, and if so, how they are motivated differently from non-poor farmers. To fill in this research gap, this paper illuminates three potential factors as sources of heterogeneous behaviors on crop diversification between poor and non-poor farmers (subsistence requirement, balanced dietary intakes, and stabilization of market income) and provides their empirical evidence. 

（Papers on the subsistence constraint）

・"Generalizing the Subsistence Constraint for Broad Issues in Development Economics" (with Aya Suzuki)  pdf  (Updated on January 19)

Highlights: This paper introduces the subsistence constraint into the standard consumer problem. The subsistence constraint is suitable for graphical representation and can easily illustrates behaviors of poor households. For application, the subsistence constraint is used as a conceptual foundation for my empirical papers above. This paper derives microeconomic properties of the subsistence constraint while maintaining its mathematical generality.
